ROPE-COUPLING AND SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 263,176, dated August22, 1882.

- Application filed April 1'i,1se2. (ModeL) To all whom it may concern:

Be it known that I, FREDERICK W. HAWES, of Algona, in the county ofKossuth and State of Iowa, have invented a new and ImprovedRope-Coupling and Snap-Hook, of which the following is a full, clear,and exact description.

The object of my invention is to provide a new and improved snap-hookwhich can readily be attached to ropes or round'straps.

The invention consists in a hook provided with a groovedshank to which alatch is pivoted, which is provided with a cam-projection and with jawsfitting against the sides of the hook. into which grooved shank the ropeor round strap is passed, and a grooved strip provided on its innersides with studs is placed on it, which strip is pressed, upon the ropeby the cam-projection of the latch when the latch is swung down, andthus holds the rope to the shank. The jaws of the latch catch on thesides of the hook, and thus assist inv holding:

the latch closed, as will be fully set forth hereinafter.

Reference is to be had to the'accoinpanying longitudinal elevation ofthe snap-hook, show-' ing it provided with a roller for suspending itfrom a breast-strap.

The shank A of the hook B is grooved longitudinally in its inner side,and is provided at its outer end with two lugs or ears, 0, projectingfrom the grooved sides of the shank. Between these lugs or ears U alatch, D, is pivoted, the end of whichis adapted to rest on the end ofthe hook, which latch is provided, near its free end, with two jaws, E,adapted to be passed over and against-the sides of the hook, which isprovided with two shoulders, a, against which the inner edges of thejaws E are adapted to rest. The latch D is provided at its pivoted endwith a grooved camprojection, F. A strip, G, which is grooved so as tofit on the rope or round strap H, is placed in the groove of the shankA, and is provided on its inner surface with a series of studs, J, andon its outer surface with a series of flat transverse grooves orrecesses, K. The grooved surface of the shank A is provided at the outerend-that is, at or near the jaws G-with a series of studs or teeth, L.The end of the shank of the snap-hook can be provided with a groovedroller, M, for suspending this snaphook from a breast-band, as shown inFig. 5.

The operation is as follows: The latch D is raised and the end of therope or round strap His passed into the groove of the shank A, and thegrooved strip G is placed on the rope, with the studs J on the surfaceof the rope, the strip G being under the cam-projection F. By swingingthe latch D over and upon the .hook B, as indicated by the arrow, thecamjprojection F will press on the strip G and will force the studs Jand the teeth L into the rope,

and the edge of the cam projection will pass into or catch on one of thetransverse grooves or recesses K on the outer surface of the strip G,andwill thus hold the strip Gr and the rope firmlyon the shank A, and willprevent withdrawing or pulling the rope from the shank.

By swinging the latch'D back in the inverse" 'holds them on thethookwithout the assistance of the cam-projection F, which is not used if thehook is provided with a roller, as shown in Fig. 5.

Having thus described my invention, Iclaim asnew anddesire to secure byLetters Patent,

' 1. A rope-coupling and snap-hook made substantially as herein shownand described, with a grooved shank. and a latch pivoted to the shank,and provided with a cam-projection at its lower end, as set forth. I

2. The combination, with the hook B, provided with the grooved shank A,of the pivoted latch D, provided with a cam-projection, F, and thegrooved strip G, substantially as herein shown and described, and forthe purpose set forth.

3. The combination, with the hook 13, provided with the grooved shankA,having teeth L, of the pivoted latch D, provided with camprojection F,and the clampingstrip Gr, hav- 5 ing projections J and transversegrooves K, substantially as herein shown and described, and for thepurpose set forth.

4. The combination, with the hook B and shank A, of the pivoted latch D,provided with jaws E, fitting against the sides of the hook,substantially as herein shown and described, and for the purpose setforth.

5. The combination, with the hook B, provided with shoulders a, and theshank A, of

15 the pivoted latch D, provided with jaws E,

fitting against the sides of the hook, substantially as herein shown anddescribed, and for the purpose set forth.

6. The combinatiomwith the hook B and the grooved and toothed shank A,of the pivoted latch D, provided with a cam-projection, F, and. jaws E,and the strip G, provided with studs J and transverse grooves K,substantially as herein shown and described, and for the purpose setforth.
